I am selling this item because I purchased it here but will not be using it. It appears to have separated and settled, and the viscosity has increased. Please remove the nozzle cap and stir with a bamboo skewer or similar, and then knead well on a tile palette or the like before use. You may also dilute it with Iris solvent. Please understand that this is a used item that has been stored at home for a long time before purchasing.
